To use, apply to the stain, gently agitate with your fingers, and blot with an absorbent cloth. This is non-toxic and should be non-irritating on the skin!
Promising review:"I had terrible rust and oil stains all over the seats of my car when I bought it. I tried other cleaners to get it out, but they actually made the stains darker. I took it to the dealership to see if they could get it out and they flat out told me no, so I gave up and lived with it for almost five years. I tried this after it was recommended by a friend.I sprayed it on and literally watched the stain run right off my seat. It was amazing!I thought I was going to have to pay hundreds of dollars to replace the seats in my car because nothing else would work. This stuff really is awesome!" —Brittany
